I'd like to start by saying if I have posted this in the wrong topic, sorry.

There is a guy on Kijiji about 130 kms (approx. 80 miles) from where I live who is selling a pretty much new TRD cat back exhaust system for the current generation of Tacoma for $200. Is this a good deal?

I'd like to discuss pros and cons of having this exhaust system. Does it improve fuel consumption, by any chance? Thanks for any advice.
